To all whom it may concern:

Be it known that I, JAMES P. HYDE, of the city and State of New York, have invented an Improvement in BasinPOIamps, of which the ollowing is a specification. nut,so that the body of the bolt Clamps have been made for holding wash; into the slab, and the nut turned basins to the under side of marble slabs and distance from the slab for attaching urinals and other basins. thickness of the basin-flange. At the outer end of the leverclamp there is m, similar devicesuchas a wedge-block-that made in one or it may be a can be leaded to the proper to accommodate the less power, clamp will slip, because the corrugations receiving the cross-piece of the attaching-bolt prevent the parts changing position as the pressure is applied.

I prefer to employ the bolt 0, (shown in Fig. the same having the T-head s in one piece with the body of the bolt, and a cam-shaped projection, u,'at one side. This does not require to be leaded into the marble. hole into the marble or stone about the'same sizehas the shank of this bolt, and cut a groove in t flange. thicknesses of flanges, and there is no means for raising up the outer end of the.clamp, and in screwing up the nut the clamp frequently slips 01f the flange of the basin.

My invention is made for avoiding the difli- 4 culties that have been practically experienced with the ordinary basin-clamps. I make use of a lever-clamp the body of which is slotted is applied end of the is of great advantage, as it prevents the necessity oftaking down the slab and inverting it for leading the bolt in cases where repairs are required. The T-head 8 passes through the slot in the lever-clamp.
